So, while (say) v70 revokes MakeMKV's key, in LD mode, a pre-v70 disk will read just fine. LibreDrive mode makes it so that the revocation table is irrelevant, although it still won't decode a newer version of AACS than MakeMKV knows about. If D: gets zapped, I still have E:, another computer with BD drives, and a couple of USB BD drives I can use (for other disks, obviously) until MakeMKV is updated. That hub is then plugged into my main 7 port hub, which is hooked into a single USB plug on my imac. My "protection" is that I have multiple drives here, and it's the drive that will be lock things out, not the computer. My current setup, I have both the drives USB plugs inserted into it's own 4 port powered hub. Anime vendors aren't quite as fast to adopt new versions of AACS as theatrical releases, but they do keep up. I usually find out about them when someone says they're having an issue here on the forum, but I sometimes get them myself - my anime supplier will often ship me stuff as much as 6 weeks before the official release, and I've hit a revoking release twice on new stuff.

I haven't seen any "this movie uses AACS version XX" resources, but I have not actually gone looking for them.
